Description
Technical field
Become complete plane even the present invention relates to the shape punching press that electron rays with shadow mask passes part, the deformability of anti-drop impact is also good under the state in being assembled in cathode-ray picture tube, and can keep the planar aperture mask plate alloy thin band of the low-thermal-expansion that does not produce the phenomenon that arches upward, also relate to by control annealing softening characteristic, anti-drop impact deformability is improved, and the above-mentioned planar aperture mask plate of keeping low heat expansion property is an alloy thin band with Fe-Ni-Co.
Background technology
The color cathod-ray picture tube is by showing image on the fluor that will impinge upon the face glass inboard from the electron beam that electron beam gun penetrates.By magneticaction controlling electron beam direction is deflector coil.For electron beam is impinged upon on the fluor of regulation, be provided with the mechanism that is divided into pixel unit in the front of face glass, be called as shadow mask board or colour-selecting mechanism.The shadow mask board that the color cathod-ray picture tube is used roughly is divided into: shadow mask board material etching and processing is become drawing the hole grid mode that is located on the frame material after carrying out the shadow mask mode of drawing and be etched into the curtain shape after point-like or the slit-like with applying big tension force tensioning on the above-below direction.Variety of way all has relative merits, and any mode all is used on market.
But, carrying out a lot of trials aspect the exploitation of the plane picture that display frame is set as flat condition.At this, so-called plane picture is meant that existing sphere display frame has almost completely approaching plane configuration.One of bigger problem is how to make shadow mask and hole grid near flat condition in the time of the picture of cathode-ray picture tube will being set as flat condition.Though all have a difficult problem separately,, the surface that makes shadow mask by punching press is compared with the mode of establishing of drawing that the hole grid are such near flat condition, is considered to more difficult (for example, NIKKEI ECTRONICS, 128 pages of 1999.7.26 (No.748)) basically.
This be because, make because shadow mask carries out drawing with metal sheet, thus with draw the mode of establishing different, must rely on the conformal power of self to keep shape, if not sphere then can not be kept shape basically.In addition, the planar aperture mask plate is that shadow mask board is set as almost flat condition, so be difficult to keep shape.In order to address this problem, has only the shadow mask board of raising intensity.At this, said " shadow mask board intensity ", different with the implication of the intensity (for example intensity that obtains by tension test) of general metal, be meant the cathode-ray picture tube assembling after, whole cathode-ray picture tube is impacted, whether cause the shadow mask board distortion.Specifically, cathode-ray picture tube is fallen from certain altitude, whether the test shadow mask board is out of shape.Improve anti-such shock-produced deformation, promptly improve the exploitation of the shadow mask board of anti-drop impact deformability (below, be called dropping strength), be necessary to flat tube.
In addition, require flat tube to have the good phenomenon characteristic that arches upward.That is, along with shadow mask board from the sphere complanation, the input angle of electron beam on four angles of shadow mask board that penetrates from electron beam gun becomes acute angle.That is to say, this means that then electron beam carries out miscontacting of screen, will produce the problem of color displacement as long as shadow mask board is offset slightly because of thermal expansion.Therefore, must develop thermal expansion than the remarkable low low-thermal-expansion shadow mask board of existing shadow mask board.
Though be not as object with the planar aperture mask plate, but as the trial that improves thermal expansion character and shock-resistance, such scheme has been proposed in patent documentation 1, that is be that alloy (super Invar) is made shadow mask and reduced thermal expansivity, by the Fe-Ni-CO that will contain 2～7 quality %Co.But, when only containing Co2～7 quality %, will before punching press, carry out shadow mask board after the anneal and be set as under the planar situation not ability drop impact.In addition, such scheme has been proposed in patent documentation 2, promptly, by at Ni be the Fe-Ni of 34～38 quality % be contain in the alloy among Ti, Zr, B, Mo, Nb, N, P, the Cu one or more, add up to 0.01～1.0 quality %, prevent to cause buckling because of the impact in when assembling, but at thermal expansivity greater than 10 * 10
-7/ ℃, shadow mask board is set as under the planar situation, can not meet the demands aspect the color displacement suppressing.
Material for shadow mask is after the alloy material of predetermined component is used for example vacuum induction melting stove (VIM stove) melting, be cast as ingot, carry out hot rolling and cold rolling after the forging, carry out clean annealing and cold rolling then repeatedly, roll after processing with passivation at last carries out finally cold rolling, is rolled to the specific thickness of 0.05～0.3mm scope.The thickness of slab of the various material for shadow mask of making by etching and processing is generally 0.05～0.30mm, and it is the material of 0.1～0.13mm that the planar aperture mask plate of particularly drawing type uses thickness of slab.Cut then and to become the plate of regulation wide, obtain material for shadow mask.After the material for shadow mask degreasing, photo-resist is coated on the two sides and figure is dried by the fire molten and after the video picture, carries out etching and punching processing, another one ground cuts off, and becomes the material for shadow mask unit.
Annealing under the temperature more than 700 ℃ in non-oxidizing atmosphere, for example reducing atmosphere in the material for shadow mask unit, is endowed press formability.In the preannealing method, before etching, final cold rolling material is carried out above-mentioned annealing.After aligning processing, be configured as planar aperture mask plate form by punch process.
At last, after the planar aperture mask plate after the drawing carries out degreasing, at atmosphere or CO/CO
2Carry out melanism in the gas atmosphere and handle, form black oxide film from the teeth outwards.Drawing type of the present invention " planar aperture mask plate ", be for example to have an outer surface curvature radius R:100, the above and planeness (maximum height of picture curved face part/active area diagonal-size) of 000mm: below 0.1%, almost completely near the shadow mask board of plane configuration.

Embodiment
Below, the limitation of the invention reason is illustrated.
(1) about Ni, Co
Fe-Ni-Co among the present invention is that the Ni content of alloy bar is 30～35 quality % scopes.In addition, Co content is 2～8 quality % scopes.
If Ni content is less than 30 quality % or greater than 35 quality %, then thermal expansivity increases, and is not suitable for shadow mask.
Co reduces thermal expansion, and the yield strength that the while also helps behind the recrystallize improves.Therefore, must add more than the 2 quality %, if addition greater than 8 quality %, then makes the magnetic properties variation, so add by the scope of 2～8 quality %.
(2) about Mn, impurity and associated element
A) C content
If C content is greater than 0.10 quality %, and then the generation because of carbide makes the etching and punching reduction, and alloy bar is not suitable as the shadow mask blank.Therefore, the upper limit with C content is defined as 0.10 quality %.
B) Si content
If Si content then makes the etching and punching reduction of alloy billet, so be not suitable as the shadow mask blank greater than 0.10 quality %.Therefore, the upper limit with Si content is defined as 0.10 quality %.
C) Al content
If Al content is greater than 0.05 quality %, and it is remarkable then to form the alumina series inclusion, makes the etching and punching reduction of alloy bar.Therefore, the upper limit with Al content is defined as 0.05 quality %.
D) Mn content
Mn is in order to make the S that reduces hot workability become harmless composition and to be contained in the iron-based alloy.If its content is few, then can not obtain effect of sufficient.But if its content is greater than 0.5 quality %, then alloy bar hardening, its processibility variation.Therefore, the upper limit with Mn content is defined as 0.5 quality %.Best, recommend to add 0.05～0.5 quality % scope.
E) S content
If S content then makes the hot workability of blank significantly reduce greater than 0.005 quality %.Therefore, the upper limit with S content is defined as 0.005 quality %.
F) P content
If P content then makes the etching and punching reduction of alloy bar greater than 0.005 quality %, is not suitable as the shadow mask blank.Therefore, the upper limit with P content is defined as 0.005 quality %.
(3) about the recrystallize characteristic
Because dropping strength is with relevant as the yield strength under the shadow mask state, so require to have carried out the yield strength height after the anneal before the drawing under 700～950 ℃ of temperature.In order to realize desirable yield strength, must be that such Fe-Ni-Co is an alloy, promptly, the generation grain size number is the recrystallized structure more than 9.5 when having carried out annealing in 15 minutes under 750 ℃ of temperature, and, the generation grain size number is the recrystallized structure more than 8.5 when having carried out annealing in 15 minutes under 850 ℃ of temperature, when the recrystallize characteristic departs from this regulation, can not obtain enough dropping strengths as shadow mask.
(4) about tensile strength
The recrystallize characteristic is relevant with the tensile strength of material (finishing finally rolling).As long as tensile strength is more than the 630MPa, just can obtain above-mentioned recrystallize characteristic.
(5) about final rolling preceding annealing and final rolling draft
In the present invention, by depressing greatly of grain refining in the final annealing before rolling and final rolling process, be that alloy is given above-mentioned recrystallize characteristic to Fe-Ni-Co.That is, be under the state of the small grains more than 8.0 by the final resulting grain size number of annealing before rolling, be to depress rollingly greatly more than 30% as if carrying out draft, then obtain desirable recrystallize characteristic.The draft of final rolling process can not obtain desirable recrystallize characteristic less than 30% o'clock.Therefore, in the present invention, will be defined as more than 8.0, the draft of final rolling process will be defined as more than 30% by the final resulting grain size number of annealing before rolling.Preferred final rolling draft is more than 50%.
Grain size number is measured according to the method for JIS G 0551 defined.In addition, rolling draft (R) is pressed the following formula definition.
R＝[(t
0-t)/t
0]×100％
At this,
T: the thickness after rolling
t
0: the thickness before rolling
(6) about (200) the face X-ray diffraction intensity component ratio in the final annealing before rolling
In the present invention, when final annealing before rolling, (200) face X-ray diffraction intensity component ratio is adjusted into below 90%.(200) face X-ray diffraction intensity component ratio is defined by following formula.
(200) face X-ray diffraction intensity component ratio=I
200/ (I
111+ I
200+ I
220+ I
311) * 100%
In above-mentioned formula, I
Hk1The X-ray diffraction intensity of expression (hk1) lattice plane.(200) face X-ray diffraction intensity component ratio in the annealing before finally rolling is brought influence to the characteristic of final stocking.That is, if (200) face X-ray diffraction intensity component ratio greater than 90%, then work hardening can reduce.Therefore, (200) face X-ray diffraction intensity component ratio is greater than 90% o'clock, even finally depress greatly when rolling, tensile strength also reduces.Because tensile strength is relevant with the recrystallize characteristic, so, then can not obtain desirable recrystallize characteristic if tensile strength reduces.So (200) face X-ray diffraction intensity component ratio is adjusted into below 90%.
(111) face, (200) face, (220) face, (311) face are received in the definition of (200) face X-ray diffraction intensity component ratio as the diffraction lattice face.This is because these 4 diffraction lattice faces are that the Fe-Ni-Co as object is the main diffraction lattice face of alloy among the present invention.
X-ray diffraction intensity (CPS) is measured with the general X-ray diffraction meter that uses.The pipe ball adopts Co pipe ball.Measured X ray diffraction intensity (CPS) has the method for the integrated value of the method for height of peaking and peaking.In the present invention, the integrated value of peaking.

At this, I
Hk1The X-ray diffraction intensity of expression (hk1) lattice plane.Diffraction X ray intensity (CPS) is measured with the X-ray diffraction meter.The pipe ball adopts Co pipe ball.In measuring diffraction X ray intensity (CPS), obtained the integrated value of peak value.The pre-treatment of measuring sample is to remove upper layer by chemical grinding (etching).Removing upper layer is the influence that is formed at lip-deep metamorphic layer in order to eliminate.Removal amount is made as about 5% of thickness of slab.5% removal amount is set on the basis of confirming thickness of slab inside (200) intensity distribution.
Tensile strength before the annealing represents that thickness is the tensile strength (MPa) of the product of 0.12mm.Product grains degree (750 ℃), expression thickness is the heat test (750 ℃ * 15 minutes: the grain fineness number non-oxidizing atmosphere) of the product of 0.12mm.Product grains degree (850 ℃), expression thickness is the heat test (850 ℃ * 15 minutes: the grain fineness number non-oxidizing atmosphere) of the product of 0.12mm.Annealing back yield strength is that the product of 0.12mm has been imagined annealed thermal treatment (8%H to thickness before the expression drawing shadow mask

On the other hand, comparative example 1 because the intermediate rolling draft is up to 78%, thus final rolling before (200) face diffraction X ray intensity component ratio in the annealing to surpass claimed range be 90%.It is 8.0 that grain fineness number in the final rolling preceding annealing also is lower than claimed range.Therefore, tensile strength, product grains degree (750 ℃), product grains degree (850 ℃) depart from claimed range before the annealing of comparative example 1, and the yield strength of having imagined after the annealed thermal treatment is low.
The scope that the final rolling draft of comparative example 2 does not meet the demands.Therefore, tensile strength, product grains degree (750 ℃), product grains degree (850 ℃) before the annealing of comparative example 2 depart from claimed range, and the yield strength of having imagined after the annealed thermal treatment is low.
(200) face diffraction X ray intensity component ratio in the annealing before comparative example 3 final rolling, final annealed grain size number, final rolling draft in rolling before rolling all do not satisfy claimed range.Its result, the yield strength of having imagined after the annealed thermal treatment of comparative example 3 all is being Schwellenwert among the embodiment.
